Other vehicles or the server recognizes the autonomous vehicle by applying the overall length, overall width and overall height of the autonomous vehicle to the received point. If the volume of the autonomous vehicle is changed, a precise point of the position of the autonomous vehicle is not provided, and thus, there is the risk of an accident. That is, in the above conventional method of providing position information of a vehicle, if the volume of the vehicle is increased, i.e., if baggage is loaded into the vehicle or a door of the vehicle is opened, detailed information about such a situation is not provided to other vehicles.
